He didn't say he was going 90. The cop claimed he was going 90. He said:

I used to think fighting a speeding ticket wasn't worth it until I finally did ... and it was worth it.

In my state, the court generally lowers the fine and points a bit if you show up with a lawyer. I'm generally pretty discreet about my speeding (never will I buy a red car again!) use a V-1 and I've earned one ticket in the last 10 years. I have no points at this time.

But I'd still fight it.

My bad - I already convicted the OP for doing 90 in a 65 zone. The original comment is still valid, however, about doing 90 in a 65 zone being a reasonable speed.

I have no problem with trying to fight a traffic ticket. More power to you....
